Not quite sure which board to use for posting this issue, so I try here.
I'm trying to power a 5V led strip using a powered USB hub (to which my Pi is also connected to).
However, it works with one hub (goobay 4 port) but it doesn't work with the other one (D-Link 4 port) and I'm not sure why.
This are the specs I could find out:
voltage: 5V, power: 3,6W, so current should be 3,6W/5V = 720 mA
goobay hub (works):
no specs found
D-Link hub (doesn't work):
max current of 500 mA per port. It has a fast charging port for mobile devices but i couldn't find out it's max current.
I should mention that the hub works fine with the Pi and all other devices.
I would at least expect a weak glowing of the led strip with 500 mA but it doesn't.
Any idea why it works with the goobay hub but not with the D-Link hub?
